User focus activated voice recognition

Abstract

One embodiment provides a method, involving: receiving, at a device, voice input comprising at least one command; identifying, using an image of the user, a direction of user focus; and responsive to the identifying that the direction of user focus is directed toward the device, performing an action based on the at least one command. Other aspects are described and claimed.

What is claimed is: 
     
       1. A method, comprising:
 receiving, at a device, voice input comprising at least one command; 
 thereafter identifying, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device; 
 detecting a shift in user focus directed toward the device after the voice input is at least partially received; and 
 responsive to detecting the shift in user focus, performing an action based on the at least one command. 
 
     
     
       2. The method of  claim 1 , wherein the image of the user is derived using at least one sensor; and
 wherein the at least one sensor is selected from a group consisting of: an image capture device, a video capture device, a range imaging device, and a 3D scanning device. 
 
     
     
       3. The method of  claim 1 , wherein the identifying a direction of user focus is based on a head location of the user. 
     
     
       4. The method  claim 1 , wherein the identifying a direction of user focus is based on a gaze location of a user. 
     
     
       5. The method of  claim 1 , wherein the image of the user is derived from a plurality of sensors. 
     
     
       6. The method of  claim 1 , further comprising:
 placing the device in a low power state based on identifying that the direction of user focus is not directed toward the device for a predetermined time. 
 
     
     
       7. The method of  claim 1 , further comprising
 waking up the device from a low power state based on identifying that the direction of user focus is directed toward the device. 
 
     
     
       8. The method of  claim 1 , further comprising changing a visual characteristic of the audio capture device in response to the user focus being directed toward device. 
     
     
       9. The method of  claim 1 , further comprising playing an audible notification in response to the user focus being directed toward the device. 
     
     
       10. An information handling device, comprising:
 a processor; 
 an audio capture device operatively coupled to the processor; and 
 a memory that stores instructions executable by the processor to: 
 receive, at the audio capture device, voice input comprising at least one command; 
 thereafter identify, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device; 
 detect a shift in user focus directed toward the device after the voice input is at least partially received; and 
 responsive to detecting the shift in user focus, performing an action based on the at least one command. 
 
     
     
       11. The information handling device of  claim 10 , wherein the image of the user is derived using at least one sensor; and
 wherein the at least one sensor is selected from a group consisting of: an image capture device, a video capture device, a range imaging device, and a 3D scanning device. 
 
     
     
       12. The information handling device of  claim 10 , wherein the identifying a direction of user focus is based on a head location of the user. 
     
     
       13. The information handling device  claim 10 , wherein the identifying a direction of user focus is based on a gaze location of a user. 
     
     
       14. The information handling device of  claim 10 , wherein the image of the user is derived from a plurality of sensors. 
     
     
       15. The information handling device of  claim 10 , wherein the instructions are further executable by the processor to:
 place the information handling device in a low power state based on identifying that the direction of user focus is not directed toward the information handling device for a predetermined time. 
 
     
     
       16. The information handling device of  claim 10 , wherein the instructions are further executable by the processor to:
 wake up the information handling device from a low power state based on identifying that the direction of user focus is directed toward the information handling device. 
 
     
     
       17. The information handling device of  claim 1 , wherein the instructions are further executable by the processor to:
 change a visual characteristic of the audio capture device in response to the user focus being directed toward the audio capture device. 
 
     
     
       18. A product, comprising:
 a storage device having code stored therewith, the code being executable by the processor and comprising: 
 code that receives, at a device, voice input comprising at least one command; 
 code that thereafter identifies, using an image of the user, a direction of user focus, wherein the direction of user focus is identified as not being directed toward the device 
 code that detects a shift in user focus directed toward the device after the voice input is at least partially received; and 
 code that performs, responsive to detecting the shift in user focus, an action based on the at least one command.
